An obese mom has taken nurturing her children to extremes by fattening them up with comfort food, RadarOnline.com has learned.

Larger than life mom, Cynthia Williams has admitted to feeding her sons to death after letting them gorge on a diet of pizza, doughnuts and fried chicken, and refuses to stop even though doctors have warned that she is signing their death warrant in grease.

Her bouncing boys, Joseph, 26, and Matthew, 18, now weigh a whopping 800 pounds combined, but their mom still keeps plying them with high-calorie food.
